Advice On Vin #

[gt bandit]

Hello all - I hope Santa left something special !

Would it be wrong to assume that if a Car had a Vin # DIRECTLY after a Known verified CS that it was also a CS.

Example

8R01C157601 = Marti report Verified CS.
8R01J157602 = Looks like a CS - but Unsure.

Also did the J code CS come off the same line as a C code ?

do the Last 5 digits change for different engine codes or is it just sequential body numbering that dictates the last 5 numbers.

If I'm not mistaken, the CS's were mixed in the line right along with the regular mustangs. They were usually run in batch's. As far as assuming that because a car may have a VIN that is directly after a known CS is a CS, I would still run a Marti report just for piece of mind. I think I would be safe in saying the "J" code cars came off the line as a "J" code, 302 vs 289. But, on the other hand you may have a "C" code car that once the carb and intake are pulled you'll notice a 302 stamping in the oil galley. Ford did this because they ran out of 289 blocks but, still had orders to fill so they used the 302 block with 289 heads and tagged them as "C" code cars. Also, the last 5 digits have nothing to do with engine size (sequential body numbering only). Your 5th digit over (8R01"S") identifies your particular engine. I'm sure there are other's here on the site that can add more info on the above subject.

From everything I have read on this forum and that we seem to know, it would still be a guess even if the VIN numbers are sequential. From what we know, the CS's were pulled from the same lines as normal coupes. It would seem there is some probability that they were pulled in batches, but no one knows (yet). It is not clear how the CS's were built at San Jose, and something I would love to know more about.

As for J code, I thought they came roughly after the C code blocks ran out, and this would be roughly the same for coupes and the CS's. Casey

Isn`t there a way to track down people who used to work there? Putting an ad in the San Jose paper would probably work. Info they give us could be included in Paul`s book. Just a thought.

Casey, I used to believe this also, but I was looking through Paul's 1996 book and noticed that the C's and J's are intermixed throughout. In fact, the first one he had listed as a production run car was a J and the last one listed was a C. Go figure!:undecided As for production runs vs. individual cars pulled off a line, it could have gone either way. I've worked in production plants before and they either could have picked a day and run all CS's that day down the line or they could have had a team that would pick cars at random, pulled them aside and modified them one at a time before picking the next one coming down the line. I've seen it done both ways. Until we have every CS documented or find someone that actually built them, I don't think we'll really know for sure.

What about the VIN # in the windshield and under the drivers fender do they match?

Steve, thanks. I am always learning something new. I guess what I was remembering was that some C codes actually got a 302 block later in 68, even though they are marked as a C code. What you are saying is that J codes were available earlier. Cool. Casey

YES, and also under the passenger side fender.
